DRIVING MECHANISM.

SPECIFICATION forming part of Letters iatent N 0. 622,207, dated April 4; 1899.

Application filed April 10, 1896. Renewed September 6, 1898. Serial No. 690,355. (No model.)

To (all, 21/71 0772 it may concern:

, Be it known that I HERMAN B. COLL-iNs, of Fulton, in the county of Oswego, in the State of New York, have invented new and usef ul Improvements in Driving Mechanism, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in driving mechanism particularly applicable for use in actuating ventilating-fans and other devices, and has for its object the production of a mechanism which is economically manufactured and is highly effective and durable in use; and to this end it consists, essentially, in the combination, construction, and arrangement of the component parts of the driving mechanism.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure l is a vertical section, partly in elevation, of my improved driving mechanism shown as operatively connected to a ventilating-fan. Figs. 2 and 3 are horizontal sections taken, respectively, on lines 2 2 and 3 3, Fig. 1. Fig. 4 is a vertical section taken on line 4, t, Fig. Fig. 5 is a top plan of the detached revoluble head or part of my driving mechanism, one of the supports for the actuatingwheels being shown as operatively connected thereto. Fig. 0 is a transverse section taken on line 6 0, Fig. 1. Fig. 7 is a section showing a slightly-modified construction of my invention, and Fig. 8 is a vertical section of a further modi.iied construction of my invention.

A represents a revoluble head or part, B a driver, and O actuating-whee1s interposed between the revoluble head or part and the driver for communicating motion from one to the other.

The revoluble head or part A is connected in any desirable manner to any suitable device to be driven, as a fan D, here shown as partly broken away, and the driver B is connected to a power-transmitting mechanism of any desirable form, size, and construction, here illustrated as an electric motor E. It is obvious, however, that, if desired, the revoin a frame F, which may also be used for sup-.

porting the motor E. The spindle to preferably extends beyond the adjacent part of the frame F, and the fan D is here shown as provided with a hub or head d, which encircles said projecting portion of the spindle a, is fixed thereto, and is provided at one end with an oil-cup d.

The driver 13 is preferably mounted upon a shaft G and may be suitably connected to said shaft or to the armature'e of the motor E. As here illustrated, one end of the shaft G is journaled in a socket a in the revoluble head or part A, and its opposite end is fixed to a hub e, which is provided upon the armature e and is formed with a socket e for receiving a spindle e fixed to the frame F. The revoluble head or part A and the spindle 6 thus form bearings for the opposite ends of the shaft G, and in order to reduce to a minimum the friction incidental to the revolution thereof suitable hardened steps, as balls 9 g, are interposed between the ends of the shaft G and the adjacent faces of said bearings. The shaft G should be properly alined with the revoluble head or partA,and consequently the stationary part of the motor E is adjusted laterally by suitable means, as screws f, and is then held in its adjusted position by clamping-screws f, which force said stationary part of the motor against a shoulder f formed upon the frame F.

The actuating-wheels C are usually connect ed to the revoluble head or part A and serve to support said head or part A, which usually depends therefrom. Said wheels 0 engage a peripheral face I) of the driver B and generally revolve on axes arranged at an angle with each other, being here illustrated as loosely mounted on diverging spindles c, fixed to in-' clined supports H, projecting from arms A, formed upon the revoluble head or part A. The supports H are preferably provided with spindles 7L, journaled in the arms A for permitting automatic lateral adjustment of the wheels C toward the axes of the revoluble head or part A and the driver 13. During this automatic lateral movement of the wheels C the revoluble head or part moves endwise, and consequently said head or part should be supported so as to be capable of a limited endwise movement. The arms A are usually slitted and provided with clamping-screws A which may, when desired, clamp the spindles It from movement, and thereby hold the supports II in their adjusted position. The friction incidental to the revolution of the rollers C is materially reduced by hardened steps, as balls 0, which engage the lower ends of the spindles c and are mounted upon adjustable supports or screws 0 secured to the lower ends of said rollers C. The wheels 0 also engage a suitable track or engaging face F, formed upon the frame F, and in order to facilitate their efficient engagement with said track or face F and the engaging face 1) of the driver 13 said wheels are adjustable lengthwise of their axes. This adjustment is effected by moving the spindles c endwise in the arms II, which, as best seen at Fig. 5, are slitted and are provided with clamps h for normally holding said spindles in their adjusted position.

In the illustrated construction of my invention the actuating-wheels O are utilized to drive the revoluble head or part A at a less speed than the driver I To effect this result, I preferably form said actuating-wheels with faces 0 c", which are of unequal diameter and engage the faces Z) F, and consequently a considerable difference in speed is obtained in a limited space and the use of a driver of comparativelylarge diameter is permitted. It is apparent, however, that the ratio between the diameters of the faces. 0 0 may be varied, as desired, or that the faces of the rollers engaged with the face I) may also engage the face F. Moreover, any suitable means, as washers B, interposed between the driver 13 and the hub 6 may be used for depressing said driver a greater or less distance in order to present a surface of greater or less diameter to the wheels 0, and thus vary the speed transmitted by my invention.

As preferably constructed, the frame F is provided with two tracks F, arranged one above the other, and the wheels 0 are each formed with two faces 0' of less diameter than the face 0 and consequently the rollers are effectively supported in position. The bearing-faces c c' of the wheels 0 are preferably formed of the outer edges of yielding rings or disks suitably secured to the body of the rollers, and said faces are preferably provided with engaging rings 0 composed of material which is somewhat harder than the remaining portions of the faces 0 c" and is softer than the faces Z1 F. The rings 0 serve to maintain the desired regularity in the contour of the engaging faces of the wheels 0, but may obviously be omitted, if desired.

In the practical operation of my invention I have ascertained that it is advisable to provide for an automatic lateral adjustment of the portion of the driver 13 provided with the engaging face Z), although such adjustment of the driver may be prevented, if desired. I usually render said portion of the driverB capable of lateral adjustment by providing the inclined face 1) upon one extremity thereof, detachably connecting its opposite extremity to the power-transmitting mechanism, as the motor E, and providing said driver with a longitudinal cavity Z1, which extends throughout the greater portion of its length and is of greater diameter than the shaft G. The lower extremityof the driver I provided with the engaging face Z), is thus free to move laterally independently of the shaft G. As here illustrated, the driver 13 is loose on the shaft G, and its extremity, unprovided with the face Z), closely fits said shaft and is driven by an arm E, fixed to the hub of the motor E and detachably engaged with shoulders at said extremity of the driver 13, Fig. 6. By thus connecting the driver B to the mechanism for revolving the same said driver is free to move endwise without liability of disen gagement from the arm E, although its upward movement is limited by the hub c, which is normally engaged thereby when the washers B are dispensed with.

In the preferable arrangement of my in vention the supports II are free to swing inwardly and the revoluble part or head A and the fan D are suspended from the actuatingwheels 0. The weight of the parts A C I) thus tends to force the actuating-wheels C toward the driver B and to increase the friction between their adjacent faces Z) c for insuring positive rotation of the wheels C. This tendency of the wheels 0 also causes a greater or less upward tendency of the driver B, which may be varied by changing the inclination of the faces I) c c" F.

The upward tendency of the driver B may be entirely obviated by operating the clamps A so as to hold the-spindles it from movement in the arms A, and thus prevent the supports H from swinging toward the axis of the driver 13. In this event the weight of the driver 13 may be relied upon as the force for frietionally engaging the faces b o or a spring or other device well known to those skilled in the art may be employed for effecting the desired engagement of said faces. I have therefore shown at Fig. 7 a driver B, the adjacent portions of actuating-wheels C and a spring 3 for engaging said parts.

IVhen my invention is applied to ventilating-fans, I preferably use the alternating type of motors, the armatures of which revolve with great rapidity and are more or less liable to effectundue heating of the parts. In order to obviate this undesirable result, the driver B is provided at its upper end with a suitable fan B which causes a circulation of the air between the adjacent parts of my invention. The armature e may also be provided, as illustrated, with inclined arms or blades 6 for effecting a similar circulation of the air.

In devices of this character it is highly important that an ample supply of oil be provided, and consequently the upper end of the hub e of the armature e, the base of the frame F, and the upper ends of the actuatingwheels 0 are respectively formed with oilchambers 6 F and O, whence the oil escapes to the rotating parts of my invention through suitable passages formed in the spindle or bearing e the frame I and the spindles c.

The current for actuating the motor D may be controlled by any suitable means, as a switch I, connected to a sleeve A encircling the spindle a; but as the construction of this switch forms no part of my invention it is unnecessary to herein specifically illustrate and describe the same. The sleeve A is engaged by a pin A, which is arranged in a slot or aperture (1 in the spindle a and is connected to an operating-piece A movable lengthwise of a chamber a that extends from the slot or aperture a to the end of the spindle a. A spring a normally elevates said sleeve, and the operating-piece extends beyond the spindle (L for permitting retraction of said operating-piece and sleeve against the action of the spring a. The switch 1, previously mentioned, is preferably so constructed that its operating parts are moved with each down movement of the sleeve A and operate to either make or break the circuit to the motor E.

At Fig. 7 I have shown a slightly-modified form of myinvention particularlyapplicable for driving a fan D supported bya column or standard D In this construction of my invention the rotary head or part A is arranged above the driver B the wheels O and the motor E all of which parts are, however, of substantially the same construction as the corresponding parts previously described.

The operation of my improved driving mechanism will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be particularly noted that the parts revolve with a minimum amount of noise and friction and are readily adjusted and that owing to the lateral adjustment of the portion of the driver provided with the face I) said driver revolves without increased friction when the engaging faces of the actuating-wheels are more or less untrue. The exact detail c011- struction and arrangement of the component parts of said mechanism may, however, be somewhat varied without departing from the spirit of my invention, and hence I do not herein specifically limit myself thereto.
